Walmart, which currently offers free two-day shipping on orders over £35, on Monday expanded that service[1] to “millions of additional items” sold by third-party sellers on Walmart.com. While Amazon does not have a minimum basket size for two-day shipping, customers must pay the annual £119 Prime membership fee to access the service.Since acquiring same-day delivery startupShipt last December for £550 million, Target has rapidly expanded its same-day delivery operations.

Shipt (which is priced at £99 annually) is now available in 46 states and in hundreds of markets.[2]Shipt is only one piece of several fulfillment investments new to Target this year. The company will also expand its curbside pickup program Drive Up to nearly 1,000 stores.

Cornell said Drive Up has been the company’s highest rated service and that orders are delivered to customer’s cars on average in less than two minutes. While not new, customers can also take advantage of delivery from store, one-hour order pickup and its Restock essentials delivery service. A marketing campaign, Run and Done, will highlight the nuances of these delivery options to customers.

Cornell said the combination of investments in stores, fulfillment and private label brands has spurred its traffic and sales growth over the last several quarters. Target in August boosted its guidance after announcing records in traffic and sales, laying out expectations to spark sales growth in line with the 4.8% comps growth the company delivered in the first half of the year. Digital sales also increased by 41%.

It’s no surprise that Target’s some 1,800 stores are at the center of its overall growth strategy, considering 50% of digital orders are fulfilled in stores. Last March, Cornell announced a £7 billion investment in stores and digital operations. This includes the remodeling of 600 stores by the end of 2018 and 1,000 by the end of 2020.
